LCD screens, on the other hand, produce light all the time. When an LCD screen needs to produce a black pixel, it just blocks the light from being shown and energy is being spent no matter what. In fact, on thinner LCD models, black screens actually end up using more energy!

So if you’re on an LCD screen, stop worrying. For those still using CRT screens, you may want to keep Blackle.com as your homepage for now.

Hey Bobmark, there's no contradiction. LCD screens and OLED screens are designed differently, and he's right that OLED screens use less power to show black pixels. Note that this only holds true for ABSOLUTE BLACK. If there's even a tiny dash of color, that pixel won't actually save energy.

You may could also include, that even while LCD displays do still need the same amount of power for black pixels (or even more), OLED displays do indeed not light black pixels (because there is no backlight like on LCD displays, but subpixels with the basecolors which get lit up, what isn't needed for black pixels) and therefore indeed also save power, not just old CRT monitors.
